| 20080236332 | Reciprocating to rotary mechanical conversion device - A mechanical conversion system for receiving input from a toroidal engine that outputs an oscillating motion. The system has a gear set with facing bevel gears that mesh with radially mounted pinions. The bevel gears are mounted on a splined input shaft via bearings and one-way clutches. An overrunning clutch is coupled with each bevel gear. As the input shaft rotates in one direction, the overrunning clutch of one bevel gear is engaged and drives the one gear in the first direction, while the overrunning clutch of the second bevel gear is disengaged and allows the second bevel gear to overrun the input shaft. The overrunning clutch is a type known as a MECHANICAL DIODE®, which engages within 4.5 degrees of rotation, without significant slippage. | 10-02-2008 |
| 20090173186 | DECLUTCHING MECHANISM - A declutching mechanism includes a chassis, a first gear rotatable relative to the chassis about a first gear axis fixed relative to the chassis, and a second gear selectively engageable with the first gear. The declutching mechanism includes an eccentric arrangement having a first shaft with a first shaft axis and a second shaft with a second shaft axis offset from the first shaft axis. The first shaft is non-rotatably fixed to the second shaft and selectively rotatably mounted in the chassis. The second gear is rotatably mounted on the second shaft. A holding feature selectively holds the eccentric arrangement in a first position. With the eccentric arrangement being held in the first position by the holding feature, the first gear and the second gear are in meshing engagement. With the eccentric arrangement being released by the holding feature, gear separating forces cause the eccentric arrangement to rotate about the first axis to a second position, thereby disengaging the first gear and the second gear. | 07-09-2009 |

| 20100263481 | DRIVE CONVERSION MECHANISM ENABLING CONSTANTLY MESHED GEARS IN A DRIVE INPUT GEAR TRAIN - A drive conversion mechanism includes a rotatably mounted output shaft, a pair of output gears mounted on the output shaft so as to rotate independent of one another and relative to the output shaft and being displaced from each other axially along the output shaft, and a pair of one-way clutches arranged about the output shaft. Each clutch is connected to one of the output gears and extends about the output shaft in respective orientations that are the reverse of each other such that the one-way clutches can only drivingly engage the output shaft at alternate times, and thus not at the same time, so as to cause the output shaft to rotate in a same single direction as the output gears are driven in opposite directions relative to each other by an input train of constantly meshed input drive and idler gears. | 10-21-2010 |
| 20110094334 | REVERSING TRANSMISSION - The REVERSING TRANSMISSION includes a shaft, a retainer, a spacing collar, a plurality of reversing members, two gears and two covers. The holder is sleeved on the shaft with spaced sliding notches formed thereon. The spacing collar is mounted on an outer surface of the retainer. The reversing members each includes two spaced swing plates with two reversed spiral teeth dented on two diagonal half surfaces of the two spaced swing plate. The reversing members slide into the sliding notches of the holder with two swing plates distributed at different side of the spacing collar. Each of the gears has a group of spiral teeth formed on the inner side for engaging with the group of spiral teeth of the reversing members, and cogs formed on the outer circumference surface. The covers are mounted on two opposite ends of the holder to keep the reversing member in position. | 04-28-2011 |
